en.Wedoany.com Reported - AXIA Energia has launched a total investment plan of R$3.53 billion for transmission infrastructure, involving 44 large-scale projects in southern Brazil, covering expansion, reinforcement, and modernization, with phased delivery expected to continue until 2029. Of this plan, R$2.98 billion is allocated to Paraná state, R$431 million to Santa Catarina state, and R$120 million to reinforce and improve the power system in Rio Grande do Sul state.
Marcelo Calvet, Director of Generation and Transmission Implementation at AXIA Energia, stated that this investment package underscores the company's commitment to modernizing and expanding transmission infrastructure in the southern region. Projects being executed in 2026 and planned for the coming years will enhance system reliability and availability, improve power supply quality for millions of people, and strengthen the operational security of the National Interconnected System (SIN). The company is investing in more modern, efficient assets that meet the highest technical standards, with a focus on ensuring infrastructure robustness to meet the current and future demands of Brazil's electricity sector.
This series of projects has been approved by the Brazilian National Electric Energy Agency (Aneel). Once fully operational, it is expected to increase the company's Annual Permitted Revenue (RAP) by R$172.72 million. In Paraná state, 19 projects are underway, notably a R$2.1 billion investment in partnership with Itaipu for the modernization of Bipole 1 of the High-Voltage Direct Current (HVDC) transmission system at the Foz do Iguaçu substation. This infrastructure is strategically important for transmitting part of the power from this binational plant to the Brazilian market.
Work began in 2024 and is expected to be completed by the end of 2026, followed by an auxiliary operation phase from 2027 to 2029. Additionally, AXIA Energia will invest R$834 million in reinforcement and improvement projects at substations in Curitiba, Londrina, Ivaiporã, and Foz do Iguaçu. In Santa Catarina state, the company is executing 15 large-scale projects. In the western part of the state, the Chapecoense substation, part of Batch 9 from the 2024 Aneel auction, is one of the company's main transmission expansion projects. This project will receive a benchmark investment of R$191 million from Aneel, with commercial operations expected to begin in the second half of 2026. The state's investment package also includes R$240.6 million for the modernization of substations in Palhoça, Blumenau, Joinville, Campos Novos, Xanxerê, Itá, Pinhalzinho 2, Siderópolis, and Jorge Lacerda A. In Rio Grande do Sul state, 10 transmission network reinforcement and improvement projects are planned, including investments in the Gravataí 2 and 3, Passo Fundo, Santo Ângelo, and Caxias 5 substations.
